Lawrence Igl, PhD
Larry Igl is a Research Ecologist at the USGS Northern Prairie Wildlife Research Center in Jamestown, North Dakota.
His research interests are avian ecology and conservation, with an emphasis on grassland, wetland, and agricultural ecosystems in the Midwest and Great Plains. Specific areas of interest include avian responses to habitat management and disturbances, Farm Bill and agriculture programs, grassland bird ecology, cowbird brood parasitism, and nesting ecology. He has conducted surveys of breeding, migrating, and wintering birds throughout the southern, central, and northern Great Plains. Recent investigations include a long-term evaluation of breeding bird communities in grasslands enrolled in the Conservation Reserve Program in North Dakota, South Dakota, Minnesota, and Montana; an eco-immunology study of New World Blackbirds; a study relating wetland management to mercury in songbirds and ducks; an evaluation of the effects of livestock stocking rates on breeding birds in grasslands managed by the U.S. Forest Service; and an investigation of the response of grassland birds to adaptive management treatments that are being used to restore floristic composition of native grasslands owned by the U.S Fish and Wildlife Service.

Historical and recent records and first nest records of Henslow's sparrow in North Dakota
The northwestern limit of the Henslow's sparrow (Ammodramus henslowii) breeding distribution occurs in southern Minnesota and central Wisconsin. In North Dakota, observations of Henslow's sparrows are reported infrequently, and there are no published nest records in the state. Herein, we summarize and review previous reports of Henslow's sparrows in North Dakota and document the first two nest recAuthorsJill A. Shaffer, Lawrence D.

The Bufflehead Bucephala albeola breeds predominantly in Canada and Alaska (USA). Evidence suggests that the species may have recently expanded its breeding range southward into central and south central North Dakota. This paper presents data on observations of Buffleheads during the breeding season in Kidder County, North Dakota, 1994-2002, and discusses the possibility that the species has not eAuthorsL.D. IglMale Brown-headed Cowbird Attacks and Kills a Nestling
I observed a male Brown-headed Cowbird (Molothrus ater) attack and kill a nestling of an unidentified passerine in a grassland field in Day County, South Dakota, in June 2000. The killing or removal of nestlings by female cowbirds has been reported by others, but this behavior has not been documented previously in male cowbirds.AuthorsL.D. IglBrown-headed cowbirds in grasslands: Their habitats, hosts, and response to management
The brown-headed cowbird (Molothrus ater) is an obligate brood parasite whose numbers have increased in recent decades to the potential detriment of the species that they parasitize. Thus, most management efforts focus on discouraging brown-headed cowbird parasitism or controlling brown-headed cowbird populations. Keys to discouraging cowbird parasitism or controlling populations of brown-headed cAuthorsJill A. Shaffer, Christopher M. Goldade, Meghan F. Dinkins, Douglas H. Johnson, Lawrence D. Igl, Betty R.

The Northern Mockingbird (Mimus polyglottos) is a common bird in the southern United States that has been expanding its breeding range into the northern United States and southern Canada.
